Living with MMN
Narrator:You're about to hear from Jen, a real patient living with Multifocal Motor Neuropathy.
Remember, the following is only representative of Jen's experiences. Every patient's experiences are unique. The following should not be taken as medical advice, and you should speak with your doctor about any questions you have about your health or treatment.
Jen: One of the key things for me with managing MMN is my support system. My best friend is absolutely amazing. My family has been amazing, and then on social media I found a group of people that are diagnosed with the same thing as me, and we talk, and we lift each other up, and we ask each other questions, and we support each other.
Every day is a challenge. It's not easy. You just learn how to deal with your new normal.
When someone asks me how I am, I always say, "I'm fabulous." And they ask me why, and I say, "Because every day is fabulous. Some days are more fabulous than others." And I truly believe that.
